NEVADA OIL AND GAS WELL DATABASE MAP
NEVADA BUREAU OF MINES AND GEOLOGY
Open-file Report 2001-07
NBMG NVOILWEL
2001
Prepared by Ronald H. Hess, Geologic Information Specialist
This information should be considered preliminary. It has not been edited or checked for completeness or accuracy. The original NVOILWEL data base is maintained in PC-File database format. UTM location coordinates were added to the NVOILWEL database and then used to generate shapefiles in ARCVIEW version 3.2a for development of the Nevada Oil and Gas Well database map.
Oil well location accuracy to 1:100,000 scale. These data should not be plotted at a scale greater than 1:100,000. This data set is in UTM, zone 11, NAD 27 projection. The shape file version of this data set is located in the shape file directory. The base data shapefiles listed below are also located in the shapefile directory. A dBase version of this database is located in the dBase directory and includes the 1996 version of this data set as well. Also included in the Read1st directory are several text files that list the oil and gas wells included in this release.
The database attributes associated with this release of the Nevada Oil and Gas Well database include:
API: American Petroleum Institute ID number
County: County name
Permit: State permit number
Operator: Company that drilled or currently operates well
Well: Well name
S: Section number
T: Township
R: Range
Partsect: Quarter section location
Distfromli: Distance from section line in feet
Permit_iss: Drilling Permit issue date
Compl_date: Date well completed
Td: Total depth drilled
Elevation: Elevation of well in feet
Tops: Geologic tops and markers in feet from surface
Tests: Listing of DSTs and intervals tested
Logs: Listing of logs and intervals available at NBMG
Samples: Listing of samples available at NBMG
Show: Shows noted for well
Conf: Confidential Status
Plot: Legend field for plotting wells
Status: Current status of well
Oil_field: Name of oil field
UTMN: UTM northing, zone 11, NAD27, meters
UTME: UTM easting, zone 11, NAD 27, meters
As part of the digital data release for this project, several digital base layers of Nevada data in Shapefile and Arc/Info export file format, designed to be used at 1:1,000,000 scale, are included on the CDROM with this project. They are:
County_p.shp Statewide county
polygon coverage
County_a.shp Statewide county
boundary arc coverage
Cities.shp Major
towns in Nevada
Roads_a.shp Major roads
in Nevada
nv_1x2.shp Polygon
coverage of 1x2 degree USGS topographic map boundaries
nvqdp.shp
Polygon coverage of 7.5 minute USGS topographic map boundaries
tr_p.shp
Township and Range polygon coverage
tr_a.shp
Township and Range arc coverage
ARC/INFO export files of the above coverages are located in the E00 files directory.
A 1:1,000,000-scale, black and white, georeferenced raster graphic of the Nevada state base map is located in the NV_DRG directory.
Also included are 18 USGS digital raster graphic maps (DRG), 1:250,000-scale, topographic maps in tiffw format. Each map covers an area of 1 by 2 degrees of latitude and longitude. This set of scanned maps covers all of Nevada. The maps are georeferenced in UTM, zone 11, NAD 27 projection and can be used with various GIS and graphic software applications. These map files are located in the DRGs1x2 directory. The names of these map files are:
Caliente.tif
Death_Valley.tif
Elko.tif
Ely.tif
Goldfield.tif
Kingman.tif
Las_Vegas.tif
Lovelock.tif
Lund.tif
Mariposa.tif
McDermitt.tif
Millett.tif
Reno.tif
Tonopah.tif
Vya.tif
Walker_Lake.tif
Wells.tif
Winnemucca.tif
Each of the above files has an additional file by the same name but ending with ".tfw". This is the world file that contains projection information for each raster graphic map.
FGDC Metadata are located in the metadata directory. This readme file is located in the READ1st directory and in the root directory. A black-and-white and a color version of the Oil and Gas Well location map in jpeg format is located in the directory called graphic. ARCEXPLORER, free viewing software, is located in the software directory. Also located in the software directory is a readme file "Free_viewing_software.htm" that should be read before installing the software. It lists the capabilities of and limitations of ARCEXPLORER.
